sPooLJNc- AoHaNEf SPECIFICATION forming part of Letters Patent No. 585,198, dated June 29, 1897.

Application filed March 19, 1896. Serial No. 583.908. (N0 model.)

To all whom it ntay concern:

Be it known that I, JOHN WV. FOSTER, of VVestfield, county of Hampden, State of Massachusetts, have invented an Improvement in Spoofing-Machines, of which the following description, in connection with the accompanyin g drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to improve spoofing-machines, whereby the yarn or thread of cotton, wool, or silk may be wound more rapidly.

The machine is provided with a drop wire or lever to actuate a leg-lever or other device of a stop-motion mechanism when a yarn or thread breaks or becomes too slack, and I have combined with this drop wire or lever devices to automatically lift it in position to be rethreaded. I have also provided novel means for insuring the delivery of the yarn or thread from the end of the spool supplying the same to be wound on a conical or other shaped tube or holder, and the spindle carrying said spool may be rotated very slowly, if desired, to prevent any loss of twist in unwinding the yarn or thread from the end of the spool. I

Figure 1, in side or end elevation, shows a sufficient portion of a spoofing-machine to enable my invention to be understood, the support for the spindle carrying the spool being broken out and the spindle being shown as moved inwardly toward the center of the machine out of its true Working position, with its end under the usual guide-eye, to thus save space on the drawings,the cone on which the thread is to be wound being omitted. Fig. 2 is an enlarged section of the spindle, spool, and spindle-cap; Figs. 2 and 2 details to be described; Fig. 3, a detail showing the face of the drum, a cone-holder and cone, and the yarn or thread guide and its support, the guide being actuated by the groove of the drum, the winding-roll and its carrying-arms being omitted. Fig. at is an enlarged detail showing part of the drum with its peculiarshaped groove and traveler of the yarn or thread guide arranged therein; and Fig. 5 shows, detached from Fig. 1, the yarn or thread guide and the reversing-spring.

The frame A, of suitable shape to contain the working parts, has a shaft A, on which is mounted a drum A or a series of drums having each a groove running diagonally about it for the reception of a traveler from a thread-guide to be described, the said drum or drums being of such size as to wind a conical or straight cop-tube at each side thereof, as in United States Patent No. 535,616, granted to me, and dated March 12, 1895.

Fig. 3 shows a yoke or carrier to, such as may be used to hold a conical shell 1", on which the yarn or thread may be wound.

I will first describe my improvements in the drum.

It is an object in this class of machines to make the drum as light and thin as possible, and heretofore the periphery of the drum has been of uniform thickness and has been provided with a shallow groove extended about the drum, in which entered a shallow traveler connected to the thread-guide. These machines are run at a high speed, for it is a great desideratum to spool the greatest number of yards of yarn or thread possible in a given time. I have found in practice that the practical speed of the drum is limited to the strength of the traveler and the rapidity with which the thread-guide may be reciprocated without breaking. The larger the diameter of the drum the greater its surface speed and the faster it will rotate a cop and the more yarn or thread it will wind on a coptube at each rotation.

Heretofore the practical diameter of the drum has been found to be twelve inches, and the thread-guide will run practically in a groove in the surface of such a drum. I have found it practicable to use a drum of thirteen and three-eighths inches diameter.

It will be remembered that the surface of the drum travels at the fastest speed and that as one approaches the center of motion thereof the speed of movement of the parts of the drum decreases.

To enable me to actuate the thread-guide a to be reciprocated at the usual practical speed which is effected by a twelve-inch drum and yet increase the speed of rotation of the cop to a speed which would be derived from the surface velocity of, say, a drum for thirteen and tl'iree-eighths inches in diameter, I

have provided the inner side of the periph cry of the drmn with a rib a and, as best shown in Fig. 5, I have cut a groove through said drmn and into the rib, leaving in the rib side walls located at a distance, say, of substantially one and three-eighths inches from the periphery of the drum, and into this groove I have placed the traveler a, its carrying-pin a" being extended into a hub a of the thread-guide carrier (4 which hub enters a wider part of the groove in thcperipheryof the drum, the hub preferably not touching the walls of the groove in said periphery. In this way the slower moving part of the drumviz., the side walls of the groove in the ribacts frictionally against the traveler a and said side walls, traveling at a slower speed than the side walls of the groove in the periphery of the drum, act in greatly reducing the friction and wear on the traveler.

In the old form of drum the traveler could not be oiled, because the oil escaped to the outside of the drum and was taken up on the windingroll s, lying against the drum, and was by it put onto the yarn or thread, soil ing it.

To enable the traveler employed by me to be oiled and thus greatly reduce its friction when being moved, I have provided each inner side wall of the groove in the rib with a like oil pocket or groove a, having its mouth a little wider than its bottom, and I have provided the bottom of each of said grooves with suitable eduction-holes a7, said holes being outwardly inclined, as shown best in Fig. 4, so that oil put into the groove in which the traveler runs will by centrifugal action be forced into the pockets, and if too much oil will issue through the holes (6 onto the interior of the drum, where it will do no harm and can be wiped. off from time to time.

The thread-guide carrier a runs on a bar a held in suitable supports 1), and lest the blow of the groove in reversing the threadguide should be too hard I have combined with the bar and guide a suitable spring 7L, (see Figs. 1 and (5,) against which the ends of the guide strike at the ends of its stroke, the said spring taking the shock of the stroke of the guide, thus relieving the traveler and its pin and starting the thread-guide, so that it will quickly com mence its return stroke with the minimum of strain on the traveler, so that the latter is not worn and the pin not strained and will run for a very long time.

The arms I) support a rock-shaft 6 having upwardly-extended arms Z1 which have open forks to receive the winding-roll s, which acts just as in the patent referred to, said shaft having a depending arm Z), to which is jointed at b a bar I), fitted into a guide-box Z1 the bar having at its under side a suitable projection Z2, with which cooperates a spring Z), having, preferably, two holding-recesses, in one or the other of which said projection will rest. This bar has pivoted on it a lever M, the inner or heavier end of which is normally down, as in Fig. 1, the said lever having a hook which is acted on when raised by one of the teeth of a ratchet m, fast on a rotating shaft at common to said patent, but designated by different letters.

The yarn or thread 9 is led from a spool e, to be described, through a guide-eye 0, over a beam 0 thence through an eye in the droplever c connected to a collar 0, loose on a stud 0, held in an ear rising from the arm 0, said collar having a toe o The yarn or thread is led from the droplever to the thread-guide a, and the lever is held by the thread with its eye above the top of the drop-lever guide 0 but when the yarn or thread breaks the drop lever dcscends and strikes the front end of the lever h causing its other end to be engaged by the stop-wheel m, such engagement of the lever causing the bar I) to he slid to the right in Fig. 1, turning the rock-shaft b in the direction to remove the winding-roll from the drum. I utilize this movement of the rockshaft to reset the drop-lever, for I have conneeted to the arm Z1 of the rock-shaft a rod (Z, attached at its other end to a lifting device (1. (Shown in Fig. 2 as a yoke having cars to span the ear of the arm c, the ears having holes to receive the pin 0 As the rod (1 is drawn to the right the under side of the lifting device acts 011 the toe c and turns the collar in the direction to lift the eye end of the drop-lever above the guide o leaving it in position to be ret-hreaded and obviating the necessity of the operator engaging the drop-lever to lift it by hand.

I have connected the upper ends of the arms b by a bar (1 and on one of the caps (1", used to hold the bar a in Fig. 1, I have placed a stud d, on which I have mounted a starting-lever d the upper short cam-shaped end of said lever (see Fig. 2 being adapted when the lever is moved by the operator in the direction of the arrow in Fig. 2" to act on the bar (I and turn the rock-shaft Z1 in the direction to cause the winding-roll to again contact with the drum and be rotated to recom m ence the winding.

The spool c rests on a grooved collar 0 of a whirl c, surrounding loosely a dead-spindle 6 the end of the whirl being reduced in diameter and resting on a step c.

The whirl has above its grooved collar 6 an extension a which has fixed to it a tubular sleeve 6 extended up through and above the top of the spool, where the upper end of the tube (see Fig. 2) receives upon it and supports clear of the spool a metal cap 6'', having a circular flange e to overlap and inclose the head of the spool. The spool fits the tube loosely, and the yarn or thread is led up or off from the end of the spool, it during its delivery running or traveling about the edge of the cap.

I may, if desired, provide the groove of the collar c with a band c driving the same slowly from any suitable moving shaft of; the

' slowly to thus obviate taking out any of the twist in the yarn.

The spring h (see Fig. 5) is connected to a block it, fast on the rock-shaft b, but this .invention is not limited to the exact shape shown for the said spring, and the shape may be varied without departing from my invention.

The thread-guide a is pivoted on the carrier a and is slotted at its upper end and is of such length that when the winding-roll s is thrown away from the drum to stop winding the said roll will act against the pivoted thread-guide and turn it outwardly far enough to cause it to release the thread and leave it lying on the top of the bar and roll, so that as the traveler continues to slide back and forth the thread-guide does not move the thread with it. The dotted lines 25 above the roll 5 show the position of the tube or holder and the yarn being wound on it.

The spool surrounds the tube c loosely, so that the spool mayturn freely on the tube on the occurrence of any strain on the yarn.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a spoolin -machine, a shell-like drum having an internal diagonal rib, provided with a diagonal groove in prolongation of a diagonal groove extended entirely through the thickness of said drum, the side walls of the groove in said rib presenting traveleractuating surfaces wholly within the thickness of the body of said shell, combined with a thread-guide support, a thread-guide, and its connected traveler, the latter being actuated by the side walls of the groove in said rib, substantially as described.
